OBJECTIVES: To study the outcome of antenatally detected fetal renal tract anomalies by II/III trimester ultrasound and its co-relation postnatally. METHODS: Prospective longitudinal study between Jan- Dec 2009 conducted at Govt. Medical College Kozhikode, Kerala, India. 100 antenatal women with isolated renal anomaly in II/III Trimester were followed up. On confirmation of anomaly, renal function tests, MCU and isotope scanning were done as indicated. Neonates were scanned at end of first week of life Post natal follow up ranged between 6 weeks to 8 months. RESULTS: The incidence of fetal urinary tract anomalies was 0.75%. 88% were male babies, 45% had bilateral renal involvement. Hydronephrosis was the most common abnormality detected (79%) with good co-relation with final diagnosis (p=0.00001).On evaluation of babies with moderate -severe hydronephrosis; persisting abnormality was seen in 17.4% and 1.1% respectively. 20% (19) of babies with severe abnormalities needed confirmatory tests and 10% (10) had elevated RFT (p=0.0092) and UTI (p=0.001). 8.6% (8) of babies needed surgical intervention (PUV-6,Grade V-VUR-1,Duplex collecting system-1). CONCLUSIONS: Majority of renal anomalies found in male babies. Mild hydronephrosis resolved in 85%. Moderate - severe hydronephrosis associated with pathology postnatal. Valve ablation in PUV and unilateral MCDK showed good prognosis.
